The present invention related to an implant (1) for an intervertebral space consists of a frame (2) which is closed at the sides but open without restriction at the top and bottom and provided with an anterior lead-in face (3) and a posterior manipulation face (4). The upper (5) and lower boundary (6) of the frame (2) is convex, so that the implant (1) has an overall lens shape in the midplane (8) of the frame (2) containing the longitudinal axis (7) of the implant (1). The inner cavity (15) which is open without restriction at the top and bottom can be filled with a compressible material. The posterior manipulation face (4) of the frame (2) is provided with an aperture (9) to allow the introduction of a compression element (10) with which the compressible material can be forced out of the inner cavity (15).
